The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

Certain embodiments relate to a hold-open assembly for a door closer including a pinion operable to rotate in a closing direction and an opposite opening direction. The hold-open assembly includes a ratchet wheel, a pawl, a controller, and a driver. The ratchet wheel is structured to be mounted to the pinion for joint rotation therewith. The pawl has an engaged position in which the pawl prevents rotation of the ratchet wheel in the closing direction, and has a disengaged position in which the pawl permits rotation of the ratchet wheel in both the opening direction and the closing direction. The controller is operable to determine a release condition and is configured to transmit a release signal in response to determining the release condition. The driver is configured to move the pawl from the engaged position to the disengaged position in response to the release signal.

A servomechanism for sliding doors of furniture item is described. An eddy-currents magnetic damper (80) to dampen the door is used to brake two carriages (26) mounted slidingly on the linear guides (20) for slidingly supporting the door.

An inward-swing door driving device, including a motor, a worm wheel and worm reducer driven by the motor, a positive clutch, an unlocking cylinder and an unlocking connecting mechanism. The positive clutch includes an inner tooth, an outer tooth and an elastic element. The inner tooth is in transmission connection with the worm wheel and worm reducer, and the outer tooth is in coaxial transmission with a door shaft of an inward-swing door. The unlocking cylinder includes a cylinder push rod. One end of the unlocking connecting mechanism is in contact with the end portion of the cylinder push rod, and the other end of the unlocking connecting mechanism is connected with the inner tooth.

Provided is a motorized drive system for actuating a door, including at least one gear having a spindle axis and a drive axis, wherein the gear assembly is designed to convert a rotational movement about the drive axis into a rotational movement about the spindle axis; at least one spindle assembly having a threaded spindle which can be rotated about a spindle axis, wherein the threaded spindle is mechanically coupled to a part of the gear assembly that can be rotated about the spindle axis, and at least one drive assembly for driving the threaded spindle with a drive shaft, wherein the drive shaft is mechanically coupled to a part of the gear assembly that can be rotated about the drive axis.

A motor vehicle door anti-rattle mechanism includes male and female parts. The male part is fastened to a door of a motor vehicle and the female part is fastened to a door pillar of the motor vehicle. The male part includes an expandable member that is selectively engageable with a recess in the female part in order to inhibit relative movement between the male and female parts and, hence, rattling of the door.

An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.

A power closure actuator for powering a movable closure includes an output member configured to drive movement of the movable closure, a motor coupled through a gear reduction to drive the output member, and an integrated brake-clutch unit having an input configured to receive drive power from the electric motor. The brake-clutch unit provides independent braking and clutching between the electric motor and the output member via an electric brake actuator and an electric clutch actuator, respectively. Brake and clutch portions of the brake-clutch unit act on a rotor, and brake force can be maintained on the rotor without powering the brake actuator. A clutch disc is biased disengaged from the rotor. The integrated brake-clutch unit provides a drive state between the electric motor and the output member when the brake portion is released concurrently with the clutch portion establishing a power coupling between the clutch disc and the rotor.

Electrically-operated inward-swing double doors and inward-swing door driving devices thereof. Each inward-swing door driving device includes a sector gear in coaxial transmission with a door shaft of the inward-swing door, a driving mechanism used for driving the sector gear to rotate, and an unlocking mechanism. The driving mechanism includes a motor gear and a motor driving the motor gear to rotate.

The unlocking mechanism includes a cylinder, a cylinder push rod extending out of the cylinder, and a lock located at the end portion of the cylinder push rod. The tail end of the lock is in transmission connection with a wheel axle of the motor gear. The lock is provided with a lock rotating shaft for rotating horizontally around the lock. The lock rotating shaft is provided with an elastic element for applying twisting resilience force to the lock.

A vehicle door control system is provided, and includes a body hinge member connected to the vehicle body, a door hinge member connected to the door, a brake and a control system. The brake includes a plate pack that includes a plurality of body brake plates connected to the body hinge member, and interleaved with a plurality of door brake plates connected to the door hinge member. The plate pack is positionable in a braking state in which the body brake plates and the door brake plates are frictionally engaged with one another to provide a first resistance to relative rotation therebetween so as to hold the vehicle door in a selected position, and a release state in which the body brake plates and the door brake plates provide a second resistance to relative rotation therebetween that is less than the first resistance.
